Introduction:

In 2015, the Indian Space Research Organisation (ISRO) launched Astrosat, India’s first dedicated multi-wavelength space observatory. It marked a significant milestone in Indian space science, showcasing the country’s ability to develop advanced technology for astronomical research.

Astrosat

Features and Design:

Multi-Wavelength Capability: Astrosat is unique because it carries telescopes and detectors that can observe the universe in multiple wavelengths—ultraviolet, visible, and X-rays—all on a single satellite.
Made in India: Most of the components and instruments used in Astrosat were developed domestically, reflecting India’s growing self-reliance in space technology.

Maharashtra State Board: Class 9

Purpose and Research Goals:

Astrosat is designed to study various aspects of the Universe, including

Star Formation and Evolution: By observing ultraviolet light, it studies the birth and lifecycle of stars.
X-ray Astronomy: Its X-ray telescopes detect high-energy radiation from black holes, neutron stars, and supernova remnants.
Galaxies and Cosmic Phenomena: Astrosat examines the structure and behaviour of galaxies, including interactions between stars and interstellar matter.
Time-Resolved Observations: It monitors dynamic events in space, like the variability of pulsars and binary star systems.

Instruments on Board:

Astrosat is equipped with

UVIT (Ultraviolet Imaging Telescope): Studies ultraviolet light from distant objects.
Large Area X-ray Proportional Counter (LAXPC): Detects low-energy X-rays for studying compact objects like black holes and neutron stars.
Soft X-ray Telescope (SXT): Focuses on high-resolution imaging of X-ray sources.
Cadmium Zinc Telluride Imager (CZTI): Captures high-energy X-rays and studies gamma-ray bursts.
Scanning Sky Monitor (SSM): Surveys the sky for transient X-ray sources.
